A discharge lamp lighting apparatus is inexpensive and is capable of generally relaxing an unevenness of brightness caused by a brightness gradient of a discharge lamp. The apparatus includes an inverter 10a to receive a DC voltage, convert the DC voltage into an alternating voltage, and output the alternating voltage from a first output terminal and second output terminal, a first ballast element C11 whose first terminal is connected to the first output terminal of the inverter, a first discharge lamp 1a connected between a second terminal of the first ballast element and the second output terminal of the inverter, a second ballast element C21 whose first terminal is connected to the second output terminal of the inverter, and a second discharge lamp 2a connected between a second terminal of the second ballast element and the first output terminal of the inverter.
